	You can now proceed to install the unit using the
	<strong>emphasised</strong> files above. Installation methods vary between
	Delphi versions, so follow the instructions that apply to your version
	below. Note that <code><strong>$(DELPHI)</strong></code> represents the
	path where the appropriate version of Delphi was installed. Similarly
	<code><strong>$(BDS)</strong></code> refers to the installation path of a
	version of the Borland Development System.

<p>
	The unit must be installed into a Delphi Win32 design package. It is assumed
	that you will be installing into an existing package. You may decide to
	install into the &quot;user&quot; package:
	<code>$(BDS)\Lib\dclusr.dpk</code>.
</p>

<ol class="spaced">

	<li>
		Decide upon a suitable location into which to install the components.
		This may be a subdirectory of your <code>Borland Studio Projects</code>
		or <code>$(BDS)\lib</code> folders.
	</li>
	
	<li>
		Copy <code>PJSysInfo.pas</code> and <code>PJSysInfo.dcr</code> to the
		chosen installation folder.
	</li>
	
	<li>
		Start the Development System (selecting the Delphi Win32 personality if
		appropriate) then:

		<ul>

			<li>
				Open the required package. Select <em>File | Open</em> menu and
				choose a suitable package source file.
			</li>

			<li>
				The package will now be displayed in the Project Manager with a
				<code>.bpl</code> extension. Right click the package's entry and
				select <em>Add</em> to display the <em>Add</em> dialog box.
				Enter the full path to <code>PJSysInfo.pas</code> in the
				<em>Unit file name</em> edit box (use the <em>Browse</em> button
				to navigate to the file). Click <em>OK</em> to add the component
				to the package.
			</li>
			
			<li>
				Back in the Project Manager, check that all the added files
				appear under the package's <em>Contains</em> node. If so, right
				click the package's entry again and select <em>Compile</em>. If
				the resulting compilation succeeds a message should be displayed
				confirming that <var>TPJSysInfo</var> has been registered. The
				component should now appear in the &quot;DelphiDabbler&quot;
				section of the Tool Palette. (Note this will only appear when a
				form is selected in the designer).
			</li>
			
			<li>
				If the component does not appear the package may not have been
				installed. Install it from the Project Manager by selecting the
				package's <em>Install</em> right click menu option.
			</li>

			<li>
				Close the package project using the <em>File | Close</em> menu
				item. Accept any prompt that offers to save the package project.
			</li>
			
		</ul>
		
	</li>

	<li>
		If you wish you can now delete <code>PJSysInfo.pas</code> from the
		chosen installation folder.
	</li>
	
	<li>
		The supplied help file cannot be integrated with the IDE's help system.
		However it can be used independently of the IDE, albeit with reduced
		functionality.
	</li>

	<li>
		The demo programs can be loaded into Delphi and compiled and run as
		required.
	</li>

</ol>


<h3 id="d3">Installation with Delphi 3 to 7</h3>

<p>
	The components must be installed into a design package. It is assumed that
	you will be installing into an existing package. You may wish to use the
	&quot;user&quot; package named <code>dclusr.dpk</code> or
	<code>dclusrXX.dpk</code> (where <code>XX</code> is a version number). This
	package can be found in <code>$(DELPHI)\Lib</code>. Ensure that the chosen
	package &quot;requires&quot; <code>designide.dcp</code>.
</p>

<ol class="spaced">

	<li>
		Decide upon a suitable location into which to install the components.
		This may be a subdirectory of your <code>$(DELPHI)\lib</code> folder.
	</li>
	
	<li>
		Copy <code>PJSysInfo.pas</code> and <code>PJSysInfo.dcr</code> to the
		chosen installation folder.
	</li>

	<li>	
		Start Delphi then:
		
		<ul>
			
			<li>
				Choose the <em>Component | Install Component</em> menu option to
				display the <em>Install Component</em> dialog box. Ensure the
				<em>Into existing package</em> tab is selected. Enter the full
				path to <code>PJSysInfo.pas</code> in the <em>Unit file
				name</em> edit box (use the adjacent <em>Browse</em> button to
				navigate to the file). Choose the required package from the
				<em>Package description</em> combo box, or by navigating to the
				package using <em>Browse</em>. Click <em>OK</em> to confirm your
				selections. 
			</li>

			<li>
				A confirmation dialog box may displayed, querying whether it is
				OK to rebuild and reinstall the package. Click <em>Yes</em> to
				proceed.
			</li>
			
			<li>
				The package will now be built and a dialog box should be
				displayed stating that the <var>TPJSysInfo</var> component has
				been installed. Click <em>OK</em> to dismiss the dialog box.
			</li>

			<li>
				The component will appear on the &quot;DelphiDabbler&quot;
				palette.
			</li>

		</ul>

	</li>

	<li>
		If you wish you can now delete <code>PJSysInfo.pas</code> from the
		chosen installation folder.
	</li>

	<li>
		The provided help file can be integrated with the IDE's OpenHelp system.
		Delphi 6 and 7 also require the use of the supplied <code>.als</code>
		file. The simplest way to install help is to use my
		<a href="http://www.delphidabbler.com/software?id=chi">Component Help
		Installer Expert</a> (v2.2.1 or later). If you prefer to install
		manually,
		<a href="http://www.delphidabbler.com/articles?article=15">this
		article</a> explains the process.
	</li>

	<li>
		The demo program can be loaded into Delphi and compiled and run as
		required.
